Not perfection, but maybe as good as the 360 pad can offer in terms of a 'massage'. Realtime control and 4 programs. Better than the '360 Mega App Pack'.
More direct control over the motors.
Some variance in the 'programs'.
...(For what it is, I don't really have any criticisms.)
Though an OK novelty, a 'real' massage seems massively superior.
Some things just aren't for me. Other folk may like them. That's OK. I wouldn't want a world full of identikit people.
